Field resistance and inductance翻译
WebOne field acts as a sort of environmental field and the second, a time varying field, re- acts with the first to drive the rotor. In induction motors the ‘environmental’ field is supplied by one or more coils in the stator that create a rotating B … WebSep 14, 2024 · : A magnetic field that changes due to electromagnetic induction generates an eddy current in the core of the conductor. The energy that generates this current is converted to heat as a loss due to the electric resistance of the core material. This is referred to as an eddy current loss. Hysteresis losses

Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current creates a magnetic field around the conductor. The field strength depends on the magnitude of the current, and follows any changes in current. From Faraday's law of … See more The history of electromagnetic induction, a facet of electromagnetism, began with observations of the ancients: electric charge or static electricity (rubbing silk on amber), electric current (lightning), and magnetic attraction ( See more If the current through a conductor with inductance is increasing, a voltage $${\displaystyle v(t)}$$ is induced across the conductor with a polarity that opposes the current—in addition to any voltage drop caused by the conductor's resistance. The charges … See more Mutual inductance is defined as the ratio between the EMF induced in one loop or coil by the rate of change of current in another loop or coil. Mutual inductance is given the symbol M. Derivation of mutual inductance The inductance … See more 1. ^ The integral is called "logarithmically divergent" because $${\displaystyle \ \int {\frac {1}{x}}\ \mathrm {d} x=\ln(x)\ }$$ for $${\displaystyle \ x>0\ }$$, hence it approaches infinity like a logarithm whose argument approaches infinity. See more A current $${\displaystyle i}$$ flowing through a conductor generates a magnetic field around the conductor, which is described by See more In the most general case, inductance can be calculated from Maxwell's equations. Many important cases can be solved using simplifications. Where high frequency currents are considered, with skin effect, the surface current densities and magnetic field may be … See more • Electromagnetic induction • Gyrator • Hydraulic analogy • Leakage inductance • LC circuit, RLC circuit, RL circuit See more WebIntroduction [ edit] In addition to resistance as seen in DC circuits, impedance in AC circuits includes the effects of the induction of voltages in conductors by the magnetic fields ( …
